## Discrepancy

AIRCRAFT WAS ON AN ACTIVE FIRE MISSION WHEN FLYING BACK TO THE WATER DIP SIGHT CO-PILOT NOTICED THE NR 2 ENGINE OIL PRESSURE DROP TO ZERO, SECONDS LATER THE NG DROPPED TO ZERO THEN THE NR 2 CHIP LIGHT ILLUM PILOT RELEASED THE LONGLINE AND WATER BUCKET (THEY HEARD THE UPPER HOOK RELEASE) SHUT NR 2 ENGINE AND PROCEEDED TO SERVICE LANDING AND TO THEIR SURPRISE THEY ENCOUNTERED A HEAVY JERK AFTER 3-4 MIN OF FLYING TOWARDS SERVICE LANDING AND NOTICED THE LONGLINE AND BUCKET HAD JUST RELEASED.  A/C LANDED AT SERVICE SAFELY, AFTER SHUT DOWN INSPECTED THE OIL CHIP MAG PLUG AND DISCOVERED 3 PIECES OF MAGNETIC STEEL PARTICLES ONE BEING ABOUT 1/4 INCH IN SIZE THE OTHER 2 ABOUT 1/8 INCH.  REPLACED NR 2 ENGINE AND CHANGED NR 1 AND NR 2 ENGINE OIL.  PRIOR TO THIS EVENT (3 DAYS) NOTICED A SMALL OIL LEAK ON THE NR 2 ENGINE UNDER WHERE THE OIL FILTER HOUSING IS LOCATED, BUT COULD NOT IDENTIFY WHERE IT WAS COMING FROM.
